Liverpool are 29 league matches without defeat, a run going back to 3 January 2019, when they were beaten by Manchester City.
And should they leave Selhurst Park with at least a point, their 30-match run would make them one of only five teams to go unbeaten for so long in the Premier League.
We look at the four sides who have gone 30 matches or more without defeat.
Starting with a 3-1 home win against Hull City, Man City's 82 points from 30 matches steered them to the 2017/18 title.
Jose Mourinho's side claimed the second-longest unbeaten run as they secured back-to-back titles with a defence that conceded only 19 times in just over a year.
Who would have thought that when Arsenal left Highbury after a 6-1 victory over Southampton it would be the start of a run that put them in the history books?
The unbeaten streak extended across the whole of the 2003/04 title-winning season, giving the team the "Invincibles" tag, with Thierry Henry claiming 39 goals.
Arsene Wenger's team were denied a half-century by Man Utd at Old Trafford, with Rooney their scourge again.
